Hello,
I am looking for relations/formula that can provide me the required fiber tension for working carbon fiber material in filament winding machine.
A preliminary study reveals that the determination of the required tension for a particular fiber depends on the part diameter,pattern to be wound and material of the fiber and tension determination is done experimentally.
What range of tension should i set my filament winding machine on? what governs its determination and can it be found by calculations?
Please cite references .
regards,

There are a bunch of scientific papers out there which deal with fiber prestressing, for example
Dvorak G. J. and Prochazka P. (1996). Thick-walled Composite Cylinders with Optimal Fiber Prestress. Composites Part B, 27B, 643–649
http://www.sciencedirect.com/science/article/pii/S1359836896000017
and this one:

Maybe you are lucky and can download them for free somewhere.
Most papers dealing with optimised winding strategies (e.g. for buckling strength, end dome design for pressure vessels etc.) seem to totally disregard fiber tensioning.
